b. 131

composition: Op. 19, Bolero

No a in EE1 (→EE2)

..

In EE1 (→EE2), the engraver overlooked the notes in the chords on the 3rd and 4th semiquavers in the bar. The mistake was rectified in EE3.

b. 131

composition: Op. 19, Bolero

c1 in chords in FE (→GE)

c1 in EE

..

The version of EE is almost certainly arbitrary – nothing indicates a possibility of a Chopinesque proofreading of the edition; there is also no reason to assume an oversight of  by Chopin. Similarly, in bar 243.

b. 131-132

composition: Op. 31, Scherzo in B♭ minor

..

Just like in all similar situations, in the main text we give the notation of A (→FC), which is present also in GE2. The changes were introduced in the remaining editions: replacing both bars with one double bar in FE (→EE) and providing rests with digits cannot come from Chopin.

b. 131-132

composition: Op. 22, Polonaise

dim. in bar 132 in FE (→GE)

dim. in bar 131 in EE

..

The fact that dim. appears earlier is probably the initial version of this fragment's dynamics, changed by Chopin in the penultimate stage of proofreading of FE (→GE). In addition to moving this indication, Chopin probably added a long accent at the beginning of b. 132, emphasising the moment from which the diminuendo should begin.
